    Hi Dr,

    I wanted to tell you about some interesting new symptoms. I reached out about a failed 2nd micro-d on L5/S1 and wanted to discuss something else with you.

    About a month ago, I started getting pain in my right front of thigh which felt like a burning on the skin. This then moved to my left and is now going down both legs.

    As of last week I had a nerve conduction study done as well as an MRI of the lumbar spine. The nerve conduction study came back normal and the MRI said I had normal/healthy discs with the exception of L5/S1 where I had the micro-d.

    My Dr has no idea what could be causing this burning so wanted to see if you had any ideas. It comes on most when sitting in a chair.

    Best,

    Peter

    Burning sensation of the skin can originate from nerve damage among other disorders. If you have now bilaterally symmetrical symptoms in both thighs that now extend down the legs, peripheral neuropathy is one the differential list. See https://neckandback.com/conditions/peripheral-neuropathy/.

    This can occur from anything from Vitamin B deficiency to Lyme disease. The fact that your EMG was normal does not help the diagnosis as small fiber nerves (commonly seen in sensory nerve) cannot be tested with the EMG test. It is possible (but not probable) that the L5-S1 level is causing these symptoms. A diagnostic epidural steroid injection (see https://neckandback.com/treatments/epidural-injections-and-selective-nerve-root-blocks-diagnostic-and-therapeutic/ and https://neckandback.com/treatments/pain-diary-instructions-for-spinal-injections/) might help to rule this in or out.
